How Hearing Aids Work Video

The patient’s audiogram has to be loaded into each piece of software individually. In some cases, I have seen my audiologist enter it manually. This wastes time and there’s the possibility that the audiogram details may be entered incorrectly. The audiologist has to learn how to use all the different applications. Some applications may have specific features that the audiologist really likes and they’d like to be able to use them when fitting any aid brand. Each application has their own helpline. More number to remember and the audiologist may find themselves repeating the same problem to multiple helpline operators.

Analog/programmable hearing aids have more than one program or setting. An audiologist can program the aid using a computer, and the user can change the program for different listening environments—from a small, quiet room to a crowded restaurant to large, open areas, such as a theater or stadium. Analog/programmable circuitry can be used in all types of hearing aids. Analog aids usually are less expensive than digital aids.

All behind-the-ear hearing aids have a microphone, amplifiers and processors, a volume control, a tone hook, an ear mold, an on/off switch, and a battery compartment. Sound enters the microphone, is amplified and shaped by the processor, and is directed out the tone hook and through the earmold into your child’s ear. The earmold is specifically molded to the shape of your child’s ear. Earmolds need to be replaced fairly often as your child’s ear grows.

When you remove the hearing aids at night, the first thing you should do is carefully wipe them down with a dry soft clothe or tissue. Next, inspect the portion of the hearing aid that fits down into the ear canal. If you observe earwax accumulating at the end of the aid, you will need to remove this. Most manufacturers will provide you with a cleaning tool, which may be in the form of a brush, wire pick or combination of both. Carefully, remove the wax. Using the brush provided for you, carefully brush around and in the plastic tubing to clear out the wax. Some patients find that using an old toothbrush is an effective method for wax removal.
